**How do you set a long value?**

long: The long data type is a 64-bit signed two’s complement integer. It has a minimum value of -9,223,372,036,854,775,808 and a maximum value of 9,223,372,036,854,775,807 (inclusive). You should append ‘l’ or ‘L’ to the value explicitly used to initialize the variable; even as small as 0.

## How do you declare a long value?

Let’s see an example to use long data type with positive and negative value.

- public class LongExample1.
- {
- public static void main(String…k)
- {
- long num1=10L;
- long num2=-10L;
- System.out.println(“num1: “+num1);
- System.out.println(“num2: “+num2);

### How do you initialize a long variable?

To initialize long you need to append “L” to the end. It can be either uppercase or lowercase. All the numeric values are by default int . Even when you do any operation of byte with any integer, byte is first promoted to int and then any operations are performed.
